Study Overview

Brief Summary

The study will investigate the effects of oral ALZ-801, in subjects with Early AD who have the APOE4/4 or APOE3/4 genotype, on the biomarkers of core AD pathology. The objectives of this study include determining the efficacy and safety/tolerability of ALZ-801. In addition, the study will evaluate the extended PK profile over 8 hours in 16 subjects after 65 weeks of treatment.

Detailed Description

The LTE year 1 & 2 study will investigate the effects of oral ALZ-801, in subjects with Early AD who have the APOE4/4 or APOE3/4 genotype, on the biomarkers of core AD pathology. The objectives of LTE study are to continue longitudinal assessment of the efficacy and safety/tolerability of ALZ-801 over a total period of 4 years (2-year Core study plus 2 years of LTE).

Core study: ALZ-801 265 mg twice daily (BID) in the Core Study, Weeks 0-104

LTE year 1: ALZ-801 265 mg BID in the Core Study and the Long-Term Extension (LTE, Weeks 104-208)

LTE year 2: ALZ-801 265mg BID in the Core Study and LTE Year 1 (Weeks 104-156), and LTE Year 2 (Weeks 156-208)

Alzheon to Present New Evidence of Neurovascular Protection and Preserved Brain Microstructure from Oral Valiltramiprosate Trials in APOE4/4 Alzheimer's Patients at AAIC 2026- Alzheon will present nine posters on valiltramiprosate at AAIC 2026, featuring expanded Phase 3 APOLLOE4 and Phase 2 trial analyses with new neurovascular protection and DTI imaging evidence. - The Phase 3 trial did not meet its primary endpoint, but pre-specified MCI subgroup analyses showed clinically meaningful cognitive and brain volume benefits alongside lower ARIA rates versus placebo. - Long-term extension data through up to four years demonstrated a favorable safety profile with no symptomatic ARIA-E or ARIA-H observed in APOE4/4 and APOE3/4 carriers. - A QSP analysis will evaluate valiltramiprosate as a potential oral maintenance therapy following plaque clearance with anti-amyloid antibodies such as donanemab or lecanemab.2 months agoAlzheon Initiates Phase 1 Trial of ALZ-507, Next-Generation Oral Alzheimer's Drug with APOE4 Corrector Mechanism- Alzheon has dosed the first subject in a Phase 1 clinical trial of ALZ-507, a novel oral drug candidate designed to inhibit neurotoxic soluble amyloid oligomers in Alzheimer's disease. - ALZ-507 features a dual mechanism of action, targeting upstream amyloid aggregation while also functioning as an APOE4 corrector to enhance its anti-oligomer properties. - The investigational therapy is designed for once-daily dosing with improved gastrointestinal tolerability compared to existing treatments. - Phase 1 results will guide dose selection for future Phase 2 studies in patients with Alzheimer's disease, Down syndrome-associated AD, and cerebral amyloid angiopathy.5 months ago
